Abstract

La présente invention concerne une pointe/un cône d'obturation de canal radiculaire amélioré(e) qui peut être fabriqué(e) avec précision pour obtenir une meilleure obturation avec moins de micro-fuites. Un aspect de la présente invention concerne une pointe/un cône d'obturation de canal radiculaire moulé(e). Un autre aspect de la présente invention concerne un procédé de moulage sous pression thermique pour fabriquer des appareils d'obturation de canal radiculaire (par exemple des pointes Gutta Percha). Un autre aspect de la présente invention concerne la structure du moule pour effectuer le moulage par injection thermique. Un aspect supplémentaire de la présente invention concerne une chaîne de production comprenant le procédé d'injection thermique.
